Upgraded HEPA Filter Mod for CraftBot FLOW Generation Printer Domes

3D printing by molten polymer deposition (also known as fused filament fabrication (FFF) or fused deposition modelling (FDMTM)), as utilized by CraftBot Printers, involves high temperature melting and sintering of polymers.

Thermoplastic processing like this has been shown to emit gases and particles, which may pose a health risk. 3D printers have been shown to release ultrafine particles (UFPs) and volatile organic compounds (VOCs), which have been linked to adverse health effects.

These emissions vary by process and material, but steps should be taken to improve safety nonetheless. Utilising an enclosure along with a high efficiency particulate air (HEPA) filter helps remove UFPs from the printer emissions; the addition of an activated carbon filter has also been suggested to improve reducing harmful emissions.

This filter, along with the model file to print the fitting, will allow you to upgrade any 80mm enclosure exhaust fan to improve safety and reduce odour.

Using 3D scanning, 3D printing and Post-Processing to Produce Models for Machine Learning

On a bottling production line, bottles with caps that have been fitted in such a way that makes them fit for purpose need to be rapidly and precisely identified. In this instance there are two specific cases that need to be looked out for: a missing tamper, and a skewed cap. Machine learning offers a great solution to this problem. By training an algorithm to be able to recognise these cases removes the need for manual inspection and reduces the scope for human error.

Distributed Manufacturing: 3D Printing for All

This blog article looks at distributed manufacturing with 3D printers today, and explores some of the opportunities that it could bring in the very near future. Although not quite as advanced as the 24th-century technology imagined in Star Trek, 3D printing and distributed manufacturing could very soon revolutionise almost every aspect of our lives.
